SIUSORT
The SIUSORT keyword is valid with the BUILD, CLONE, and REORG (Online Reorg function and Reorg function) commands.
You can specify this keyword in the environment setup member (DLIGSET0) or in PLUSIN. The following table describes the Sort processing keyword.
To do this | Specify this in PLUSIN |
|---|---|
Sort and load index records internally (in the same address space). | SIUSORT(I) |
Sort and load index records externally (in separate address spaces). | SIUSORT(E) |
Internal default: (I) | |
The SIUSORT keyword enables you to sort and load indexes in separate address spaces. If you use separate address spaces to sort and load indexes, elapsed time for large indexes will be shorter. When you specify SIUSORT(E), the Index Build function creates one address space for each index.
When an SIUSORT(E) job is running, you will see a separate MVS job for each index. When all of the indexes are sorted and loaded, the output from the separate MVS jobs is merged into the original job.
The Index Build function uses the MVS proc IEESYSAS when it creates the new address spaces. The job name given to the new address spaces is in the following format:
The variables indicate the following information:
- nnnn is the JES job number for the original job.
- xx is the sequential number used to make the job name unique.
